Abstract
Background Neointimal hyperplasia and its related arterial stiffness are the crucial pathophysiological features in atherosclerosis and in-stent restenosis. Cluster of differentiation 147 (CD147), a member of the immunoglobulin super family that induces the expression of matrix metalloproteinase-9 (MMP-9) by dimerization, may play important roles in neointimal hyperplasia and may therefore be an effective target for the treatment of this condition. Here, we investigated whether a novel CD147 inhibitor SP-8356 ((1S,5R)-4-(3,4-dihydroxy-5-methoxystyryl)-6,6-dimethylbicyclo[3.1.1]hept-3-en-2-one) reduces neointimal hyperplasia and arterial stiffness in a rat model of partial carotid artery ligation. Methods Neointimal hyperplasia was induced in Sprague–Dawley rats by partial ligation of the right carotid artery combined with a high fat diet and vitamin D injection. Rats were subdivided into vehicle, SP-8356 (50 mg/kg), and rosuvastatin (10 mg/kg) groups. The drugs were administrated via intraperitoneal injections for 4 weeks. The elasticity of blood vessels was assessed by measuring pulse wave velocity using Doppler ultrasonography before sacrifice. Histomolecular analysis was carried out on harvested carotid arteries. Results SP-8356 significantly reduced MMP activity by inhibiting CD147 dimerization. SP-8356 reduced neointimal hyperplasia and prevented the deterioration of vascular elasticity. SP-8356 had a greater inhibitory effect on neointimal hyperplasia than did rosuvastatin. Furthermore, rosuvastatin did not improve vascular elasticity. SP-8356 increased the expression of smooth muscle myosin heavy chain (SM-MHC), but decreased the expression of collagen type III and MMP-9 in the neointimal region. In contrast to SP-8356, rosuvastatin did not alter the expression of SM-MHC or MMP-9. Conclusions The ability of SP-8356 to reduce neointimal hyperplasia and improve arterial stiffness in affected carotid artery suggests that SP-8356 could be a promising therapeutic drug for vascular remodeling disorders involving neointimal hyperplasia and arterial stiffness.

Abstract
Background Cluster of differentiation 40 ligand (CD40L) and rosuvastatin (RSV) affect atherosclerotic plaque stability, but little is known about their roles in extracellular matrix (ECM) production. We investigated the effects of CD40L and RSV on pre-existing advanced plaques. Methods and results Pre-existing advanced plaques were induced in apolipoprotein E-knockout (ApoE-/-) mice by the surgical placement of carotid constrictive silastic collars. Two weeks after surgery, mice were divided into the following treatment groups: control, empty adenovirus, CD40L adenovirus, CD40L adenovirus + RSV, and RSV. Mice received adenovirus via two tail-vein injections (2 × 109 pfu each) and/or RSV via intragastric administration (5 mg/kg; daily for 4 weeks). Mice in the CD40L adenovirus group exhibited increased plaque disruption rates, increased relative plaque macrophage and lipid content, reduced plaque collagen content, and increased local inflammation compared to the other treatment groups, but no significant differences in plaque area were observed among the groups. Notably, in the atherosclerotic plaques of the CD40L adenovirus group, both the mRNA and protein expression of prolyl-4-hydroxylase alpha 1 (P4Hα1) was significantly decreased, leading to a consequent decrease in the protein expression of collagen types I and III. Treatment with RSV decreased the serum levels of CD40L in a lipid-independent fashion and attenuated the effects of CD40L overexpression, particularly with respect to P4Hα1 downregulation. Conclusions CD40L destabilized advanced plaques in the carotid arteries of ApoE-/- mice, in part by decreasing P4Hα1 expression, and consequently collagen expression. These destabilizing effects were attenuated by RSV.

Abstract
Supplemental Digital Content is available in the text. Objective— Rosuvastatin has been widely used in the primary and secondary prevention of coronary heart disease. However, its antiatherosclerotic properties have not been tested in a mouse model that could mimic human coronary heart disease. The present study was designed to test the effects of rosuvastatin on coronary artery atherosclerosis and myocardial fibrosis in SR-B1 (scavenger receptor class B type 1) and apoE (apolipoprotein E) double knockout mice. Approach and Results— Three-week-old SR-B1−/−/apoE−/− mice were injected daily with 10 mg/kg of rosuvastatin for 2 weeks. Compared with saline-treated mice, rosuvastatin-treated mice showed increased levels of hepatic PCSK9 (proprotein convertase subtilisin/kexin type-9) and LDLR (low-density lipoprotein receptor) message, increased plasma PCSK9 protein but decreased levels of hepatic LDLR protein and increased plasma total cholesterol associated with apoB (apolipoprotein B) 48-containing lipoproteins. In spite of this, rosuvastatin treatment was associated with decreased atherosclerosis in both the aortic sinus and coronary arteries and reduced platelet accumulation in atherosclerotic coronary arteries. Cardiac fibrosis and cardiomegaly were also attenuated in rosuvastatin-treated SR-B1−/−/apoE−/− mice. Two-week treatment with rosuvastatin resulted in significant decreases in markers of oxidized phospholipids in atherosclerotic plaques. In vitro analysis showed that incubation of bone marrow-derived macrophages with rosuvastatin substantially downregulated cluster of differentiation (CD)36 and inhibited oxidized LDL-induced foam cell formation. Conclusions— Rosuvastatin protected SR-B1−/−/apoE−/− mice against atherosclerosis and platelet accumulation in coronary arteries and attenuated myocardial fibrosis and cardiomegaly, despite increased plasma total cholesterol. The ability of rosuvastatin to reduce oxidized phospholipids in atherosclerotic plaques and inhibit macrophage foam cell formation may have contributed to this protection.

Abstract
BACKGROUND In animal models and clinical trials, statins are reported as effective in reducing cholesterol levels and lowering the risk of cardiovascular diseases. We have aggregated the findings in animal models - mice, rats and rabbits - using the technique of systematic review and meta-analysis to highlight differences in the efficacy of statins. MATERIALS AND METHODS We searched Medline and Embase. After examining all eligible articles, we extracted results about total cholesterol and other blood parameters, blood pressure, myocardial infarction and survival. Weighted and standard mean difference random effects meta-analysis was used to measure overall efficacy in prespecified species, strains and subgroups. RESULTS We included in systematic review 161 animal studies and we analysed 120 studies, accounting for 2432 animals. Statins lowered the total cholesterol across all species, although with large differences in the effect size: -30% in rabbits, -20% in mice and -10% in rats. The reduction was larger in animals fed on a high-cholesterol diet. Statins reduced infarct volume but did not consistently reduce the blood pressure or effect the overall survival. Few studies considered strains at high risk of cardiovascular diseases or hard outcomes. CONCLUSIONS Although statins showed substantial efficacy in animal models, few preclinical data considered conditions mimicking human pathologies for which the drugs are clinically indicated and utilized. The empirical finding that statins are more effective in lowering cholesterol derived from an external source (i.e. diet) conflicts with statin's supposed primary mechanism of action.

Abstract
CONTEXT Atorvastatin is a member of the drug class known as statins, which is used for lowering blood cholesterol. OBJECTIVE The present study investigates the effect and mechanism of atorvastatin on neointimal hyperplasia after carotid artery injury (CAI) of rat. MATERIALS AND METHODS Fifty male rats were randomly divided into four groups: control group, sham-operated group, model group, and atorvastatin treatment group. The treatment group was fed with atorvastatin (10 mg/kg) with gastro-gavage at 5 p.m. every day for 28 d after surgery. The control group, model group, and sham-operated group were fed with the same volume of distilled water instead. The proliferations of intimal and medial layers were evaluated by hematoxylin & eosin (H&E) staining. The apoptosis of vascular smooth muscle cells (VSMCs) was determined by terminal deoxynucleotidyl transferased UTP nick end labeling (TUNEL) staining. Plasma concentrations of survivin and sFas were detected by enzyme-linked immunosorbent assay (ELISA). RESULTS Atorvastatin reduced neointimal formation and increased apoptosis of VSMCs in neointima. VSMCs apoptosis emerged at 3 d (8.42 ± 0.449 μm) and the intimal proliferation peaked by the end of 14 d (41.58 ± 1.64 μm). The plasma levels of survivin and sFas were gradually increased with the neointimal hyperplasia and increasingly decreased after atorvastatin treatment. The plasma levels of survivin and sFas in rats were elevated at 3 d (464.80 ± 105.27 pg/ml and 3256.00 ± 478.20 pg/ml, respectively), reached the peak of survivin at 14 d (1089.20 ± 232.32 pg/ml) and sFas at 7 d (4362.00 ± 639.92 pg/ml) and decreased at 28 d (562.00 ± 90.11 pg/ml and 2148.00 ± 257.14 pg/ml, respectively) in the model group. Compared with the model group, the atorvastatin treatment group has significantly less neointimal hyperplasia and more apoptosis of VSMCs. CONCLUSIONS Atorvastatin can inhibit neointimal hyperplasia and promote SMCs apoptosis in neointimal layers, which may be mainly associated with down-regulation of survivin and Fas expression after CAI of rat.

Abstract
OBJECTIVE While transient ischemic attack (TIA) is a well-known harbinger of ischemic stroke, the mechanisms that link TIA to subsequent strokes remain poorly understood. The overall aim of this study was to determine whether: 1) brief periods of transient cerebral ischemia render this tissue more vulnerable to thrombus development and 2) antiplatelet agents used in TIA patients alter ischemia-induced thrombogenesis. APPROACH & RESULTS The middle cerebral artery of C57BL/6 mice was occluded for 2.5-10min, followed by reperfusion periods of 1-28days. Intravital microscopy was used to monitor thrombus development in cerebral microvessels induced by light/dye photoactivation. Thrombosis was quantified as the time to platelet aggregation on the vessel wall and the time for complete blood flow cessation. While brief periods of cerebral ischemia were not associated with neurological deficits or brain infarction (evaluated after 1day), it yielded a pronounced and prolonged (up to 28days) acceleration of thrombus formation, compared to control (sham) mice. This prothrombotic phenotype was not altered by pre- and/or post-treatment of mice with either aspirin (A), clopidogrel (C), dipyridamole (D), or atorvastatin (S), or with A+D+S. CONCLUSIONS The increased vulnerability of the cerebral vasculature to thrombus development after a brief period of transient ischemia can be recapitulated in a murine model. Antiplatelet or antithrombotic agents used in patients with TIA show no benefit in this mouse model of brief transient ischemia.

Abstract
BACKGROUND Besides its lipid-lowering effect, rosuvastatin has an antithrombotic effect, the exact underlying mechanism of which is still unclear. The aim of this study was to investigate the effects of rosuvastatin on the fibrinolytic system, including tissue-type plasminogen activator (t-PA), urokinase-type plasminogen activator (u-PA) with its receptor (u-PAR) and plasminogen activator inhibitor-1 (PAI-1), in vascular endothelial cells exposed to oxidized low-density lipoprotein (oxLDL). METHODS Human umbilical vein endothelial cells (HUVEC) were cultured and divided into 7 groups: control, rosuvastatin alone (10 nM), oxLDL alone (100 mg/L), oxLDL plus rosuvastatin (0.1, 1.0 and 10 nM, respectively) and oxLDL plus rosuvastatin (10 nM) with mevalonate (100 μM). The lactate dehydrogenase activity and concentrations of t-PA, u-PA, u-PAR and PAI-1 protein in culture medium were measured, whereas the expressions of t-PA, u-PA, u-PAR and PAI-1 mRNA in endothelial cells were detected by real-time polymerase chain reaction at 24 hours after treatment. RESULTS Compared with the control group, oxLDL caused a significant increase in lactate dehydrogenase activity. It could reduce the expression of t-PA mRNA and protein (P < 0.05) and increase the expression of PAI-1 mRNA and protein (P < 0.05). Rosuvastatin could protect the endothelial cells, improve t-PA production and reduce PAI-1 production (P < 0.05), whether in unstimulated HUVEC or in HUVEC exposed to oxLDL. The effects of rosuvastatin on the fibrinolytic system could be reversed by mevalonate. No significant differences in u-PA and u-PAR production were seen among different groups. CONCLUSIONS Rosuvastatin has protective effects on oxLDL-induced damaged human vascular endothelial cells; its antithrombotic effects may be mediated by the regulation of the fibrinolytic system.

Abstract
The HMG-CoA reductase inhibitor (statin) rosuvastatin (Crestor) is widely available for use in the management of dyslipidemia, and was recently approved in the US to slow the progression of atherosclerosis as part of a strategy to lower low-density lipoprotein-cholesterol (LDL-C) and total cholesterol (TC) to target levels. Rosuvastatin has greater lipid-lowering efficacy than any of the other currently available statins, and significantly more patients receiving rosuvastatin than other statins achieve LDL-C goals. Rosuvastatin delayed the progression of carotid atherosclerosis in patients with subclinical carotid atherosclerosis, moderately elevated cholesterol levels, and a low risk of cardiovascular disease in a primary prevention trial (METEOR). The results of METEOR suggest a possible role for the earlier use of rosuvastatin in primary prevention, although more data are needed from trials examining the effects of the drug on cardiovascular endpoints. Significant regression of atherosclerosis was seen with rosuvastatin 40 mg/day in patients with established coronary heart disease (CHD) in the ASTEROID trial, supporting the use of intensive lipid lowering in secondary prevention patients (although it should be noted that it has not yet been established that atherosclerotic regression translates into improved cardiovascular outcomes). Rosuvastatin is generally well tolerated, with a similar tolerability profile to that of other currently available statins. Thus, rosuvastatin is an important lipid-lowering treatment option that has been shown to cause regression of atherosclerosis in secondary prevention patients, and has a potential future role in delaying atherosclerosis in primary prevention patients.

Abstract
Growing human atherosclerotic plaques show a progressive loss of vascular smooth muscle cells (VSMC) becoming soft and vulnerable. Lipid loaded-VSMC show impaired vascular repair function and motility due to changes in cytoskeleton proteins involved in cell-migration. Clinical benefits of statins reducing coronary events have been related to repopulation of vulnerable plaques with VSMC. Here, we investigated whether HMG-CoA reductase inhibition with rosuvastatin can reverse the effects induced by atherogenic concentrations of LDL either in the native (nLDL) form or modified by aggregation (agLDL) on human VSMC motility. Using a model of wound repair, we showed that treatment of human coronary VSMC with rosuvastatin significantly prevented (and reversed) the inhibitory effect of nLDL and agLDL in the repair of the cell depleted areas. In addition, rosuvastatin significantly abolished the agLDL-induced dephosphorylation of myosin regulatory light chain as demonstrated by 2DE-electrophoresis and mass spectrometry. Besides, confocal microscopy showed that rosuvastatin enhances actin-cytoskeleton reorganization during lipid-loaded-VSMC attachment and spreading. The effects of rosuvastatin on actin-cytoskeleton dynamics and cell migration were dependent on ROCK-signalling. Furthermore, rosuvastatin caused a significant increase in RhoA-GTP in the cytosol of VSMC. Taken together, our study demonstrated that inhibition of HMG-CoA reductase restores the migratory capacity and repair function of VSMC that is impaired by native and aggregated LDL. This mechanism may contribute to the stabilization of lipid-rich atherosclerotic plaques afforded by statins.

Abstract
RATIONALE HMG-CoA reductase inhibitors such as rosuvastatin may have immunomodulatory and anti-inflammatory effects that may reduce the severity of influenza A infection. We hypothesized that rosuvastatin would decrease viral replication, attenuate lung injury, and improve mortality following influenza A infection in mice. METHODS C57Bl/6 mice were treated daily with rosuvastatin (10 mg/kg/day) supplemented in chow (or control chow) beginning three days prior to infection with either A//Udorn/72 [H3N2] or A/WSN/33 [H1N1] influenza A virus (1×10(5) pfu/mouse). Plaque assays were used to examine the effect of rosuvastatin on viral replication in vitro and in the lungs of infected mice. We measured cell count with differential, protein and cytokines in the bronchoalveolar lavage (BAL) fluid, histologic evidence of lung injury, and wet-to-dry ratio on Day 1, 2, 4, and 6. We also recorded daily weights and mortality. RESULTS The administration of rosuvastatin had no effect on viral clearance of influenza A after infection. Weight loss, lung inflammation and lung injury severity were similar in the rosuvastatin and control treated mice. In the mice infected with influenza A (A/WSN/33), mortality was unaffected by treatment with rosuvastatin. CONCLUSIONS Statins did not alter the replication of influenza A in vitro or enhance its clearance from the lung in vivo. Statins neither attenuated the severity of influenza A-induced lung injury nor had an effect on influenza A-related mortality. Our data suggest that the association between HMG CoA reductase inhibitors and improved outcomes in patients with sepsis and pneumonia are not attributable to their effects on influenza A infection.

Abstract
OBJECTIVE To ascertain the impact of prior antiplatelet and statin therapy on symptomatic embolic events in [corrected] infective endocarditis (IE). PATIENTS AND METHODS We studied a retrospective cohort of adult patients with a diagnosis of IE who presented to Mayo Clinic (Rochester, MN) from January 1, 2003, to December 31, 2006. Patients were grouped into those who received treatment before infection or controls who did not receive treatment for both antiplatelet therapy and, separately, statin therapy. Because of the retrospective study design and thus the nonrandomized treatment groups, a propensity score approach was used to account for the confounding factors that may have influenced treatment allocation. Antiplatelet therapy included aspirin, dipyridamole, clopidogrel, ticlopidine or any combination of these agents. Statin therapy included atorvastatin, simvastatin, pravastatin, lovastatin, rosuvastatin, or fluvastatin. The primary end point was a symptomatic embolic event that occurred before or during hospitalization. Multivariable logistic regression was used to assess the propensity-adjusted effects of continuous daily therapy with antiplatelet and statin agents on risk of symptomatic emboli. Likewise, Cox proportional hazards regression was used to test for an independent association with 6-month mortality for each of the treatments. RESULTS The study cohort comprised 283 patients with [corrected] IE. Twenty-eight patients (24.1%) who received prior continuous antiplatelet therapy developed a symptomatic embolic event compared with 66 (39.5%) who did not receive such treatment. After adjusting for propensity to treat, the effect of antiplatelet therapy on embolic risk was not statistically significant (odds ratio, 0.71; 95% confidence interval [CI], 0.37-1.36; P=.30). Only 14 patients (18.2%) who received prior continuous statin therapy developed a symptomatic embolic event compared with 80 (39.4%) of the 203 patients who did not. After adjusting for propensity to treat with statin therapy, the benefit attributable to statins was significant (odds ratio, 0.30; 95% CI, 0.14-0.62; P=.001). The 6-month mortality rate of the entire cohort was 28% (95% CI, 23%-34%). No significant difference was found in the propensity-adjusted rate of 6-month mortality between patients who had and had not undergone prior antiplatelet therapy (P=.91) or those who had and had not undergone prior statin therapy (P=.87). CONCLUSION The rate of symptomatic emboli associated with IE was reduced in patients who received continuous daily statin therapy before onset of IE. Despite fewer embolic events observed in patients who received antiplatelet agents, a significant association was not found after adjusting for propensity factors. A continued evaluation of these drugs and their potential impact on subsequent embolism among IE patients is warranted.

Abstract
BACKGROUND Processes of restenosis, following arterial injury, are complex involving different cell types producing various cytokines and enzymes. Among those enzymes, smooth muscle cell-derived matrix metalloproteinases (MMPs) are thought to take part in cell migration, degrading of extracellular matrix, and neointima formation. MMP-9, also known as gelatinase B, is expressed immediately after vascular injury and its expression and activity can be inhibited by statins. Using an established in vivo model of vascular injury, we investigated the effect of the HMG-CoA reductase inhibitor rosuvastatin on MMP-9 expression and neointima formation. MATERIALS AND METHODS 14-week old male Sprague Dawley rats underwent balloon injury of the common carotid artery. Half of the animals received rosuvastatin (20 mg/kg body weight/day) via oral gavage, beginning 3 days prior to injury. Gelatinase activity and neointima formation were analyzed 3 days and 14 days after balloon injury, respectively. 14 days after vascular injury, proliferative activity was assessed by staining for Ki67. RESULTS After 14 days, animals in the rosuvastatin group showed a decrease in total neointima formation (0.194±0.01 mm2 versus 0.124±0.02 mm2, p<0.05) as well as a reduced intima/media ratio (1.26±0.1 versus 0.75±0.09, p<0.05). Balloon injury resulted in increased activity of MMP-9 3 days after intervention for both rosuvastatin treated animals and controls with no significant difference observed between the groups. There was a trend towards a reduction in the number of Ki67-positive cells 14 days after injury. CONCLUSIONS Rosuvastatin attenuates neointima formation without affecting early MMP-9 activity in a rat model of vascular injury.

Abstract
The available therapeutic options for sepsis are restricted by their effectiveness and high cost. Emerging preliminary data suggest that statins and omega-3 fatty acids (OM3FA) may be associated with improved outcomes in terms of prevention and treatment of sepsis. We sought to review the current evidence on the effectiveness of their combined administration against sepsis, by carrying out a review of PubMed and Scopus databases for relevant studies, without imposing language or time restrictions. No clinical studies were identified regarding the effect of the combination treatment with statins and OM3FA on sepsis in terms of prevention or treatment. However, there is experimental evidence that both statins and OM3FA inhibit the inflammatory process at different levels, but also enhance inhibition at those levels that are common. There are also preliminary data supporting the beneficial effect of this combination on platelet function and other haemostatic mechanisms. Appropriately designed and powered clinical trials are warranted to investigate the effectiveness and safety of the combined administration of statins and OM3FA for the prevention and treatment of sepsis.

Abstract
Background Substantial evidence suggests that high glucose (HG) causes endothelial cell damage; however, the potential mechanism therein has yet to be clarified. The aim of this study was to investigate the influence of HG on the endothelial-to-mesenchymal transition (EndMT) and its relevance to the activation of the renin-angiotensin system. Methods Primary human aortic endothelial cells (HAECs) were divided into three groups: a normal glucose (NG) group, HG group, and irbesartan (1 μM)-treated (HG+irbesartan) group. The concentration of angiotensin II in the supernatant was detected by radioimmunoassay. Pathological changes were investigated using fluorescence microscopy and electron microscopy. Immunofluorescence staining was performed to detect the co-expression of CD31 and fibroblast markers, such as fibroblast-specific protein 1 (FSP1). The expressions of FSP1 and α-SMA were detected by RT-PCR and Western blot. Results The treatment of HAECs in the HG group resulted in significant increases in the expressions of FSP1 and angiotensin II in dose-and time-dependent manners. The incubation of HAECs exposure to HG resulted in a fibroblast-like phenotype, wherein increased microfilamentation and a roughened endoplasmic reticulum structure were observed in the cytoplasm. The expressions of FSP1 and α-SMA were significantly increased in the HG group, and these changes were inhibited by irbesartan treatment (P < 0.05). Double staining of the HAECs indicated a co-localization of CD31 and FSP1 and that some cells acquired spindle-shaped morphologies and a loss of CD31 staining; however, treatment with irbesartan attenuated the expression of EndMT (P < 0.05). Conclusions These findings suggest a novel mechanism in HG-induced endothelial damage via the mediation of the EndMT by angiotensin II, which was inhibited by Irbesartan.

Abstract
Statins (3-hydroxy-3-methyl glutaryl coenzyme A [HMG-CoA] reductase inhibitors) are the most commonly used lipid-lowering drugs. Their main lipid-lowering effect is achieved by an increase in the expression of low-density lipoprotein cholesterol receptors associated with inhibition of cholesterol synthesis through inhibition of HMG-CoA reductase - the first and rate-limiting step in cholesterol synthesis. However, beyond cholesterol synthesis inhibition, inhibition of the HMG-CoA reductase affects as well the synthesis of other molecules with significant roles in different, yet often intercalating, metabolic pathways. On this basis, and supported by an increasing series of advocating epidemiological and experimental data, an extended dialogue has been established over the last few years regarding the nonlipid or "pleiotropic" actions of statins.

Abstract
Experimental models have enhanced our understanding of atherothrombosis pathophysiology and have played a major role in the search for adequate therapeutic interventions. Various animal models have been developed to simulate thrombosis and to study in vivo parameters related to hemodynamics and rheology that lead to thrombogenesis. Although no model completely mimics the human condition, much can be learned from existing models about specific biologic processes in disease causation and therapeutic intervention. In general, large animals such as pigs and monkeys have been better suited to study atherosclerosis and arterial and venous thrombosis than smaller species such as rats, rabbits, and dogs. On the other hand, mouse models of arterial and venous thrombosis have attracted increasing interest over the past two decades, owing to direct availability of a growing number of genetically modified mice, improved technical feasibility, standardization of new models of local thrombosis, and low maintenance costs. To simulate rupture of an atherosclerotic plaque, models of arterial thrombosis often involve vascular injury, which can be achieved by several means. There is no animal model that is sufficiently tall, that can mimic the ability of humans to walk upright, and that possesses the calf muscle pump that plays an important role in human venous hemodynamics. A number of spontaneous or genetically engineered animals with overexpression or deletion of various elements in the coagulation, platelet, and fibrinolysis pathways are now available. These animal models can replicate important aspects of thrombosis in humans, and provide a valuable resource in the development of novel concepts of disease mechanisms in human patients.

Abstract
Anti-inflammatory activities of statins in atherosclerosis have been well documented by both basic research and clinical studies. Statins have been introduced in the 1980s as 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors to block cholesterol synthesis and lower cholesterol serum levels. In the last three decades, statins have been shown to possess several anti-inflammatory and antioxidant activities resulting in the beneficial reduction of atherosclerotic processes and cardiovascular risk in both humans and animal models. Inflammatory intracellular pathways involving kinase phosphorylation and protein prenylation are modulated by statins. The same intracellular mechanisms might also cause statin-induced myotoxicity. In the present review, we will update evidence on statin-mediated regulation of inflammatory pathways in atherogenesis.

Abstract
Statins, in addition to their beneficial lipid modulation effects, exert a variety of several so-called "pleiotropic" actions that may result in clinical benefits. Rosuvastatin, the last agent of the class to be introduced, has proved remarkably potent in reducing low-density lipoprotein cholesterol levels. At present, no large-scale primary or secondary prevention clinical trials document either its long-term safety or its effectiveness in preventing cardiovascular events. A substantial number of experimental and clinical studies have indicate favorable effects of rosuvastatin on endothelial function, oxidized low-density lipoprotein, inflammation, plaque stability, vascular remodeling, hemostasis, cardiac muscle, and components of the nervous system. Available data regarding the effects of rosuvastatin on renal function and urine protein excretion do not seem to raise any safety concerns. Whether the established "pleiotropy" and/or lipid-lowering efficacy of rosuvastatin may translate into reduced morbidity and mortality remains to be shown in ongoing clinical outcome trials.

Abstract
Statins (HMG-CoA reductase inhibitors) exhibit beneficial effects on the vasculature independently of their cholesterol-lowering properties. These pleiotropic effects underlie the ability of statins to reduce intimal hyperplasia in saphenous vein (SV) bypass grafts by attenuating smooth muscle cell (SMC) invasion and proliferation. Although all statins can effectively lower cholesterol, the pleiotropic effects of individual statins may well differ. We therefore compared the concentration-dependent effects of 4 lipophilic statins (simvastatin, atorvastatin, fluvastatin, and lovastatin) and 1 hydrophilic statin (pravastatin) on the proliferation and invasion of SMC cultured from SV of 9 different patients undergoing coronary artery bypass grafting (CABG). The lipophilic statins inhibited SV-SMC proliferation over a 4-day period with an order of potency of fluvastatin > atorvastatin > simvastatin > lovastatin (IC50 range = 0.07 to 1.77 microM). Similarly, these statins also inhibited SV-SMC invasion through an artificial basement membrane barrier (fluvastatin > atorvastatin > simvastatin >> lovastatin; IC50 range = 0.92 to 26.9 microM). In contrast, the hydrophilic pravastatin had no significant effect on SV-SMC proliferation at concentrations up to 10 microM, nor did it attenuate SV-SMC invasion (up to 30 microM). Our data provide strong evidence that individual statins possess differential pleiotropic effects on SV-SMC function. This may be of clinical relevance in the selection of individual statins for the treatment of CABG patients.

Abstract
The urokinase (uPA)/urokinase receptor (uPAR) multifunctional system is an important mediator of migration and proliferation of vascular smooth muscle cells (VSMC). However, whether uPA/uPAR-directed mechanisms are involved in the beneficial effects of 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors on vascular remodeling remains unexplored. In this study, we have investigated the effect of the hydrophilic statin rosuvastatin on neointimal remodeling, and the role of uPAR. Using an ex vivo organ and in vitro cell culture models we demonstrate that rosuvastatin decreases injury-induced neointima formation and proliferation of medial VSMC in porcine coronary arteries, as well as migration and proliferation of human coronary VSMC. Studies on the underlying mechanisms show that rosuvastatin impairs VSMC transition from their physiological contractile to the pathophysiological synthetic phenotype. These effects are mediated, at least in part, via uPAR, as confirmed by means of rosuvastatin-directed uPAR expression and uPAR silencing in both models. Our findings provide evidence that rosuvastatin modulates VSMC phenotypic changes and subsequently their proliferation and migration, and indicate the important role for uPAR in these processes. This mechanism contributes to the beneficial non-lipid lowering effect of rosuvastatin on negative vascular remodeling.

Abstract
Aspirin, dipyridamole, cilostazol, thienopyridines and glycoprotein IIb/IIIa inhibitors represent the classical examples of the established antiplatelet agents commonly used for the secondary prevention in patients after vascular events. Obviously, the era of expanding antiplatelet regimens and indications may require new agents as the substitutes, or additions to the available strategies. However, recent results of the majority of antiplatelet trials strongly suggest boarder line advantages in clinical outcomes, and higher associated bleeding risks with the novel antiplatelet agents or/and regimens. Moreover, unexpected failures, such as lack of efficacy of clopidogrel and aspirin combination for ischaemic stroke prevention (MATCH), or use of the same antiplatelet regimen for the primary vascular prevention (CHARISMA) raise legitimate concerns that the concept 'the more the better' may not be valid. Broad use of statins, angiotensin receptor blockers and selective serotonin reuptake inhibitors may be in part responsible for the lack of impressive results with the antiplatelet therapy because each of these drug classes per se inhibits platelets. In this review, we discuss the available evidence and potential clinical significance of these findings.

Abstract
We investigated whether, in primary prevention patients with metabolic syndrome, statins affect the platelet protease-activated receptor-1 (PAR-1) thrombin receptor by performing serial measurements of its activity and the antigen expression level by flow cytometry before and during treatment. Recent data from randomized trials of statins are compatible with the possibility of clinically relevant pleiotropic effects. The use of statins is associated with a reduced thrombosis burden and diminished platelet activity, as shown in animal models and in vitro studies. Seventy patients with the metabolic syndrome who were not taking antiplatelet agents were assigned consecutively at starting doses at the discretion of the responsible clinician to 1 of 6 statins (atorvastatin, fluvastatin, lovastatin, pravastatin, rosuvastatin, or simvastatin) or to a no-statin group for 6 weeks. Platelet expression of intact (SPAN12 antibody) and cleaved (WEDE15) PAR-1 thrombin receptors were assessed by flow cytometry at baseline and at weeks 4 and 6 of treatment. At baseline, no difference was found in receptor expression. However, after 4 weeks of treatment, all statins had significantly inhibited (46% to 55%) the activated epitope of PAR-1 expression. After 6 weeks, inhibition remained, despite a slight rebound (22% to 37%). Also, a delayed pattern of inhibition of the intact PAR-1 receptor epitope was found. In conclusion, all statins inhibited the activity and antigen level of the platelet PAR-1 thrombin receptor, which has a major role in regulating platelet activity and thrombin formation. These observational data offer a plausible mechanism for the recently demonstrated pleiotropic effects of statins that may contribute to early clinical benefit.

Abstract
The aim of our study was to explore some potential pleïotropic effects of atorvastatin, after stenting in the iliac arteries of normocholesterolemic rabbits. On day 0, 27 rabbits underwent stent implantation and were randomized into either the control group (standard chow, CTRL, n = 15) or the atorvastatin group (10 mg/kg/d per os, Ator, n = 12). On day 30, the stented arteries were harvested for histomorphometry and neointimal analysis [macrophages, matrix metalloproteinases (MMP-2), tissue inhibitor of metalloproteinase-2, vascular smooth muscle cells, and collagen]. Atorvastatin did not induce significant histomorphometric and inflammatory modifications but reduced neointimal expression of MMP-2 with no modification of tissue inhibitor of metalloproteinase-2, and also induced higher neointimal collagen content (Ator vs. CTRL: MMP-2: 0.05 +/- 0.03 vs. 0.70 +/- 0.20, P < 0.01; collagen: 17.0+/-0.7%/mm vs. 12.0 +/- 1.2%/mm(2) P < 0.01). Atorvastatin treatment also induced a significant decrease in neointimal vascular smooth muscle cells and cellular density (respectively: 2.0 +/- 0.2 vs. 1.4 +/- 0.2, P < 0.05; 5406 +/- 241 nuclei/mm(2) vs. 4402 +/- 163 nuclei/mm(2), P < 0.001). Our study provides new insights into the field of MMP response to stenting and the effects of statin therapy, which could have important implications in the field of in-stent restenosis.

Abstract
PURPOSE OF REVIEW 3-Hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) are the most widely prescribed drugs worldwide for lowering cholesterol levels. In use for more than 15 years, they have demonstrated efficacy, safety, and tolerability across a broad range of patients. This class of drugs has been designed to lower the cholesterol level by competitively inhibiting the enzyme responsible for its biosynthesis and thereby to play a major role in reducing cardiovascular risk. However, both basic evidence and clinical evidence also supports the idea that reductions in cardiovascular risk are dependent on mechanisms beyond cholesterol reduction alone, such as the reduction of endothelial dysfunction, inhibition of inflammatory responses, stabilization of atherosclerotic plaques, and modulation of procoagulant activity and platelet function. RECENT FINDINGS In fact, as shown in several clinical trials, the beneficial effects of statin treatment begin earlier than its cholesterol-lowering effect. These other mechanisms could act in concert with the potent low-density lipoprotein cholesterol-lowering effects of this class of drugs to exert early and lasting cardiovascular protective effects. Recently, several studies have shown that an intensive lipid-lowering regimen with a statin provides greater protection against death or major cardiovascular events than does a standard regimen. SUMMARY This review summarizes the new findings in these pleiotropic effects and describes their impact on vascular processes.
